I am a big guy and face it most packing gear is for pencil shaped people with zero body fat. This guy that was bigger than me recommended this bag and it's the only bag that i have now for almost 20 years.
I find it a bit bulky for the temp rating as well being all down it looks like a -30 degree bag. But it has lasted and so has the bag expander that i bought. all in all it has served be well over 300+ camp tours. I do motorcycle camping now and this bag is with me hot or cold. Hot i lay on top cold get in the downs and snuggle up. It's time for a bath so i picked up some Nikway Down Wash and a dozen tennis balls. I wish it was a little bigger i have a huge shoulder width.

This bag is great when I bought it I thought the size (packed)was a bit big.
It wasnt until I got inside that I found the reason why. The width is huge, this is the first bag Ive been able to put my knees up. You can also sqirm around with no restricted movement.
The toasty warm temperature rating is a bonus at -12 (3/4 season).
The mosquito hood is great for trkking as well as sleeping but I use the pocket for my RAB silk liner. Great loft and leg room so no complaints here, looks like MTN Hardwear have done it again.

I like this bag! Well, it has given me one problem. The zipper broke & I cant seem to be able to fix it myself so I'll have to take it in somewhere. Its soft & warm though. I'm 5'2'' & I like how I fit in it. Very cozy.

I actually decided not to purchase this bag after trying it out in the store. Most stores don't keep this model in stock (it was a special order) so let me save you the time. The bag was sewn well and seemed to use quality materials, and lofted well after a few minutes on the store floor.

The problem is this: it isn't that big. Mountain Hardwear markets this bag to people who need more room. I'm a big guy, and the bag just wasn't cut well for people who move around a lot during the night. Sierra Designs Flex series works better. Also, Western Mountaineering bags fit me very well, despite claimed measurements that are smaller than the Mammoth's. Finally, this bag is heavy for its temperature rating.

You may like it, but I hope these comments help.

Contrary to some here, I like the fit of this bag much better than the elastic SD bags. This one fits me perfectly, even without the MH bag expander. I kept it anyway, for car campin' luxury! I struggled to find a bag that fit me. The NF Chrysalis kind of fit, but doesn't have a draft tube...what's up with that?!! I have been enduring a SD semi-rect. for years that prevents me from sleeping with my arms at my sides...a strait jacket. The Mammoth is perfect, in my book.
